VENTILATOR FOR REFRIGERATOR-CARS.

SPECIFICATION forming part of Letters Patent No. 585,779, dated July 6,1897.

Application filed August 3, 1896. Serial No. 601,440. (No model.)

To all whom it may concern.-

Be it known that We, J ACOB NORLING and CHARLES E. J OHNSON, citizens ofthe United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented a certain new and useful Improvement in Car-Ventilators, which is fully set forth in the following specification,reference being had to the accompanying drawings, in which- Figure 1 isa plan view of a portion of a car to which our ventilator is applied,showing the lid thrown open, but the ventilator back from theice-aperture. Fig. 2 is a similar view with the ventilator over theaperture,but not raised. Fig. 3 is a vertical longitudinal section onthe line 3 3 of Fig. 2. Fig. 4c is a similar section showing theventilator raised. Fig. 5 is a vertical cross-section on the line 5 5 ofFig. 4 in the direction of the arrow. Fig. 6 is a detail plan view of acorner of the ice-aperture and ventilator-frame. Fig. 7 is an enlargeddetail view of a portion of Fig. 3. Fig. 8 is an enlarged detail view ofaportion of Fig. 4.

Our invention relates to ventilators particularly adapted for use incombined refrigerator and ventilated cars, and has for its ob ject toprovide a structure less liable to injury and wear and more efficient inoperation than the ventilators of this general type heretofore used.

Referring to the drawings by letterfA represents a portion of a car-roofwhich is provided with ice-apertures A in the usual Way. Surroundingeach such aperture, upon three sides thereof, we construct a curb B,which is provided on its inner side with the horizontal rib b. Upon thetwo opposite sides of the curb B are secured strips B, provided on theirinner sides with horizontal ribs 1), corresponding to the ribs 2), butlocated above the same. Between the two sets of ribs 11 and Z) there arethus formed the horizontal guides B adapted to receive theventilatorframe, later described. Upon the front of the curb B issecured a strip B corresponding to the strips B, but without any rib b.

Upon the car-roof, immediately in rear of the ice-aperture, upon thatside thereof not inelosed by the curb B, we construct a hood or box C,of approximately the same area as pose hereinafter described.

ice-aperture.

that of the ice-aperture, open upon the side adjacent to the aperture.Upon the vertical sides of the hood C, part way between the roof C ofthe hood and the roof A of the car, which forms the bottom of the hood,are secured horizontal strips 0 in prolongation of the strips b. Thereare thus formed between the said strips and the roof A of the car guidesC in continuation of the guides B Upon the forward edge e of the roof *0of the hood are provided two forwardly-projecting lugs 0 which extendoutward so as'to nearly come in contact with the cover F when the latteris in its elevated position, for the pur- To the said edge 0 of the roofof the hood is hinged a lid D, adapted to swing down over and close theThe lid D comprises the lid proper, D, and the reinforced portion Dsecured to the bottom thereof, provided with the beveled edges (1. Thisreinforcement is of the ordinary construction and serves forheat-insulating purposes.

Adjacent to the hinged edge of the lid D,

secured to the under side thereof, are provided the lugs or short arms61, for an object later described. The free edge of the lid is providedwith a hasp d adapted, when the lid is closed, to be looked upon thestaple (Z secured to the roof of the car in front of the ice-aperture.

The ventilator itself comprises a horizontal frame, a cover hingedthereto, ascreen hinged to the free edge of the cover, and side wingshinged to the sides of the said cover. The frame E is rectangular andconsists of front and rear pieces E and E and side pieces E and E allprovided at their lower inner edge .with an inwardly-projecting rib orflange e.

The sides of the frame, E and E fit in the guides B and C so that theframe is adapted to be slid backward and forward from its poedge of thecover F is hinged a screen-frame G, provided withascreen G. The loweredge of the screen-frame is provided with a hasp 9, adapted to be lockedto a staple g, mounted upon the forward edge E of the ventilatorframe.To the sides'of the cover F are hinged the triangular side pieces H H.Each of the said side pieces is provided on its lower edge with a lug h,adapted to fit, when the ventilator is raised into operative position,in the notch 77., formed in the rib c of the frame sides E E aforesaid.

To refer now to the operation of the parts the construction of which ishereinabove described, when the car is to be used as a ventilated carthe lid D is thrown back and the ventilator is drawn forward into itsposition over the ice-aperture. The cover F is now raised. Thescreen-frame, screen, and side wings are swung down, the latter havingthe lugs h fitting in the apertures h of the ventilator-frame, and theformer being locked by the hasp and staple g and g. Thus the Ventilatoris locked in its raised position and cannot be lowered until unlocked.In such position it can obviously not be removed or shoved back from theice-aperture, which is thus secured against intrusion. To prevent morecompletely the sliding backward of the whole ventilator, the lugs c areformed as above described and are adapted to bear against the lower orrear portion of the cover F, should the latter be pushed back when thesame is raised.

When the car is to be used as a refrigerator-car, the ventilator isunlocked, the side wings H and the screen-frame G are swung up under thecover F, which is then lowered into horizontal position, as shown inFig. 3, and the entire ventilator is slid back into the hood or housing0. Thus it is entirely removed from the ice-aperture and secured fromany injury during the icing of the car. The lid D is swung down over theice-aperture and locked in such position by the hasp and staple d and (iThe short arms or lugs d prevent the ventilator sliding forward over theice-aperture while the lid is thus closed and hold the ventilatorsecurely in its housed position.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. In a car provided with an aperture A,

a lid D, adapted to close the same, a hood.

formed upon the car at one side of the said aperture, a movable frameadapted to slide from a position in the hood to a position over theaperture, a cover hinged to said frame, a screen hinged to the free edgeof the cover, and triangular side wings hinged to the sides of thecover, said wings and screen being adapted to support the cover in aninclined position when the ventilator is in use, and to be folded downupon the frame and the whole slid back into the hood when not in use,substantially as described.

In a car provided with an ice-aperture A, a lid D adapted to coverthe said aperture; a hood 0 formed at one side thereof; a curb Bsurrounding the remaining sides of the aperture and provided with theguides B a ventilator consisting of a frame E adapted to slide on theguides B and backward into the hood 0, of a cover hinged at one edge tothe frame, of a screen hinged to the free edge of the cover, and oftriangular side wings hinged to the sides of the cover; the said screenand side wings being adapted to hold the cover in an inclined position,or to be folded upon the same when the Ventilator is out of use; lugs72. on the lower edge of the wings adapted to secure the lower edges ofthe latter to the ventilator-frame; and means for locking the free edgeof the screen to the edge of the ventilator-frame.

4. In a combined ventilator and refrigerator car provided withice-apertures A, the curb B inclosin g three sides of each aperture, andprovided with guides B on the sides thereof; the hood 0 constructedadjacent to the remaining side of the said ice-aperture, and open uponthe side adjacent thereto; the guides 0 upon the inner sides of the hoodformed in continuation of the guides B the lugs attached to the edge ofthe roof of the hood; the lid D adapted to close the ice-aperture hingedto the said edge of the roof of the hood and provided with the shortarms d; a ventilator consisting of a slidable frame E provided with therib 6 having apertures h; a cover F hinged to the ventilator frame; ascreen hinged to the free edge of the cover F adapted to support thecover in an inclined position; means for locking the lower edge of thescreen, when the ventilator is raised, to the ventilator-frame, and theside wings H hinged tothe sides of the cover F, and provided on theirlower edges with the lugs h adapted to enter the said apertures h, tosecurethem to the ventilator-frame E; the said screen and side wingsbeing adapted to fold under the cover F when the same is lowered into ahorizontal position, substantially as described.
